## Question

Momentumm case study: shipping a real React Native product with AI help

## Answer

Momentumm came out of a very familiar problem: you ship something, you try to promote it, and you realize that momentum itself is hard to maintain.

I wanted a place where people building apps and SaaS products could plan publicly, make commitments, and build in public without the whole thing feeling like productivity theater.

So I built it.

## The Build

I built Momentumm in early January 2026 in under fifty focused hours.

Without AI, I probably would not have built it at all. If I had, I would estimate something more like one to two months of work and roughly $15,000 to $30,000 of effort.

That is the pattern I keep seeing: AI does not decide what is worth building, but it makes more experiments financially and emotionally possible.

## Where AI Helped

AI helped most with the implementation and the UX execution.

My part was deciding what the product should be, how the event system should work, which features mattered, and how the experience should feel.

The hardest engineering problem was the feed itself. I needed a flexible event model that could support real user activity cleanly and still stay legible.

## What It Proves

Momentumm was also a practical test for me. Could an AI-assisted workflow help ship a real React Native app that would make it through the Apple App Store and Google Play review process?

Yes.

That matters, because the difference between a demo and a distributed product is the whole game. Momentumm proves I can use AI to move much faster without dropping below the quality bar required for a real release. It also supports the broader point I make about [AI in development](/ai) and why a [small senior-led build](/vs/freelance-agency) can go further than people expect.
